∙ 14y agoIt is called a thermometer - used to measure temperature. The liquid in the bulb expands more than the glass when the temperature rises, so the length of the column of liquid in the tube increases with temperature.

What element makes glowing signs?
The orange colored lights seen along roadways use sodium. The white colored lights usually use mercury.
Why do people use alcohol in thermometers instead of water?
Firstly, mercury has a freezing point of about -38Co. So a mercury thermometer cannot be used below this. Alcohols have a much lower freezing point, some around -100Co . Thus they are useful at much lower temperatures. Though alcohols are usually colourless, they can easily be dyed, usually red or blue. Alcohols however have lower boiling points, and this limits the maximum temperature at which they may be used.
How do you show a female without a trait in a pedigree chart?
A normally colored circle. As a carrier of the trait, they are usually half-colored.
How can you tell if a lab thermometer contains mercury a toxic substance?
Just look at the rise or drop in the level of the liquid inside (mercury), which is usually colored red or blue or yellow, it's definitely easy and if it's grey, pay close attention. Look across for the calibrated reading and record in degree Celsius.More Detail: After taking the person's temperature, hold the thermometer up to a light where you can see the mercury line and the numbers. The higher the temp, the higher the mercury line will go. You will have to turn (rotate) the thermometer until you can clearly see the number and the lines between the numbers, much like on a ruler. The thermometer will have whole numbers, but not all of them have all of the numbers. The point at which you see where the mercury end is what the temperature is.For example, mine starts at 96, then goes to 98, then 100, etc. There are lines between the numbers 96 and 98, indicating 97, 99, etc., and there are also lines indicating the degree of the temperature in 10ths. If you take a person's temperature, and they have a fever of 99.8, then the end of the mercury line will be two lines below 100 degrees. If they have a fever of 100.5, then the mercury line will be five lines past the number 100. Most thermometers in the U.S. are in Fahrenheit, which will give you a different reading than one that measures the temperature in Celsius, so be sure you know which type you have.
What liquid is advisable to use as liquid inside the thermometer mercury or alcohol?
Rather ironically, it depends on the temperatures involved. Most thermometers use mercury. Partly, this is because the silver colour of the mercury make it easy to read, but mainly because they work over a useful range of temperatures for everyday use. However, one problem with mercury is that its melting point is -38oC; so below that temperature the thermometer would freeze - this makes it unsuitable for use in very cold environments. Alchohol thermometers (usually ethanol is used) work from around -115oC, so they are used in low temperature environments - the disadvantage with alcohol is that it vaporises at 78oC so it isn't useful in very hot environments.

What is a thin galss tube with a bulb on one end that contains a liquid usually mercury or colored alcohol?
A Thermometer. It is used to sense temperature changes.As the liquid expands and contracts with heating or cooling, when set on a calibrated scale, you can get a pretty exact reading on the amount of the changes.
